FIELD: motors and pumps.
SUBSTANCE: invention relates to propulsors for surface and underwater vessels, and can also be used for combat torpedoes. Device of the propeller for surface and underwater transport has a cigar-like shape and consists of a forward auger and auger arranged on one longitudinal axis with multidirectional continuous saber-like blades. In the middle of the propulsor there is an engine separating and propelling the front and rear augers in opposite directions, also the propeller at both ends has a nose of cone shape. To operate the propulsor with the help of an engine that drives the augers, rotate the propeller forward. Augers with multidirectional saber-like blades rotate in opposite directions.
EFFECT: increase in thrust without vibration and noise during the movement of the ship or torpedo is achieved.
